    摘要: The present invention is directed to an injection molding valve configured to prevent the leaking or stringing of injected thermoplastic from the valve. The valve includes a housing having a first bore along a length thereof and a second bore intersecting the first bore. A rotatable member is inserted through the second bore and is in communication with a lever for the actuation thereof. The rotatable member includes a hole therethrough such that when the hole is aligned with the first bore, thermoplastic may travel freely through the first bore. The second bore further includes at least one groove in communication with a port for receiving injected thermoplastic. The injected thermoplastic is hardened to form an seal therein and configured to prevent thermoplastic from leaking out of the valve housing.

    摘要: A method of sandwich molding, in which a first thermoplastic material is injected into a mold cavity followed by the injection of a second thermoplastic material expanding within the first thermoplastic material, eliminates the need for heated runner systems communicating from the injection nozzle of the injection molding machine to the mold cavity by employing a cold runner having sufficiently slow solidification time to allow subsequent injections from two injection sources. The backflow into the inactive branch is prevented by maintaining the injection nozzle against the mold until molding is complete.
